Can I use an Energizer charger with eneloop batteries?

Eneloop batteries can generally be charged with any kind of NiMH battery charger. Duracell, Energizer and no-name. But to keep things simple, you better stay away from these 2 kinds of chargers: Ultra fast chargers and Dumb chargers. Ultra Fast chargers use a very high current to charge your batteries.

Not significantly. So long as it is done using a properly designed smart charger, most NiMH batteries can be recharged in about an hour without any damage or significant reduction in their life. However, NiMH batteries must only be rapid charged with a charger specifically designed for charging NiMH batteries.

Answer: Those AmazonBasics high-capacity batteries are most likely rebranded Sanyo XX cells, so naturally you can recharge them with Sanyo eneloop chargers (or any other good-quality NiMH chargers). It charges in pairs only, and takes 12 hours to recharge any batteries - regardless of capacity. I do not recommend it.

Answer NiMH refers to Nickel Metal Hydride and NiCd refers to Nickel Cadmium. The major differences between the two types of batteries are is capacity, memory effect and environmental friendliness. NiMH batteries have high capacity, no memory effects and environmentally friendly.

If you're tempted to test an alternator by disconnecting the negative battery cable, don't do it. A good alternator may indeed keep the engine running, but it was never a good test. In the pre-computer days, you could pull it off without damaging anything. Today, you risk frying every electrical device in your vehicle.

Yes, an automobile can run without a battery, if the alternator is large enough to support all of the electrical needs. This is because your alternator is enough to keep the car alive and driving since the motor is already on, although you probably won't be able to use accessories like the radio, even turn signals.

Either the automatic gearbox prevents rolling the car at all or there is an open clutch which cannot be closed manually. So if you want to be prepared for your automatic car not starting because of a dead battery, put a jump start cable in your trunk and/or sign a membership with a road assistance organisation.

Compared to conventional battery chargers that take more than twice the amount of time to recharge batteries, the SANYO 4-position Ni-MH rechargeable battery charger can completely recharge fully discharged AA Ni-MH batteries in approximately 10 hours and 7 hours for AAA Ni-MH batteries.

A: Cold weather is often fingered as the culprit when car batteries die, but actually warm temperatures do the most damage to them. But car batteries usually go dead in cold weather mostly because damage done during the summer doesn't show up until the battery is more taxed.

Current is flowing in the battery during charging and discharge. A battery can be modeled as a voltage source in series with a resistor. Older or poor quality batteries conversely heat up more. Also, the faster the battery charges, the hotter it will get (more current means way more heat).

Outside of CA it is legal to throw single-use alkaline batteries in your regular trash however we strongly encourage you to recycle them instead. Many cities and counties will collect single-use batteries during their household hazardous waste collection events.

1.

Are eneloop lithium batteries?

A. No eneloop batteries do not fall under the travel restrictions for Lithium batteries. eneloop batteries are Nickel Metal Hydride cells and considered “dry batteries”, not lithium technology.

Which eneloop battery is best?

Overall, the best rechargeable AA battery is the Eneloop Pro. They have a high energy capacity (2500 mAh), and they perform better than similar high-capacity AAs. They can only be charged 500 times (versus 2100 times for regular Eneloops). But most people will never charge their batteries that many times.

How long does it take to charge a rechargeable battery?

One of the problems with terms like these is that the amount of time it takes to charge a battery is dependent on the capacity of the battery being charged. A charger that can charge a standard capacity AAA NiCD battery (180 mAh) in just one hour might take 8 hours to charge a high capacity NiMH (1500 mAh) battery.

No, non rechargeable batteries cannot be placed in any charger. For optimal performance, Energizer® NiMH Rechargeable batteries are designed for use with Eveready®chargers. If the charger is not properly designed, it could cause a loss of performance by the battery being overcharged, undercharging, or overheating.

Is there a rechargeable alkaline battery?

Rechargeable alkaline batteries are manufactured fully charged and have the ability to hold their charge for years, longer than NiCd and NiMH batteries, which self-discharge. Rechargeable alkaline batteries can have a high recharging efficiency and have less environmental impact than disposable cells.

Only batteries that are specifically labeled “rechargeable” should be recharged. Any attempt to recharge a non-rechargeable battery could result in rupture or leakage. We recommend that you use NiMH Duracell rechargeables. Paired with one of our different chargers, they can be recharged hundreds of times.

Q: How many times can a NiMH battery be recharged? A: Lower capacity rechargeable AA batteries of 1700 up to 2000mAh can be recharged up to 1000 times in overnight slow charge mode, while 2100 to 2400 mAh rechargeable batteries can be recharged up to 600 to 800 times in overnight slow charge mode.

A NiMH in a NiCd charger would overheat, but a NiCd in a NiMH charger functions well. Modern chargers accommodate both battery systems. It is difficult, if not impossible, to slow charge a NiMH battery. Harmful overcharge can occur when charging partially or fully charged batteries, even if the battery remains cold.

The charge time for the included 1300 mAh AA batteries is about five hours. The 11-hour timer is strictly a back-up safety feature in the event the charger doesn't turn off once the batteries are fully charged. The Value Charger will recharge any NiMH AA and AAA batteries.

Do rechargeable batteries go bad if not used?

Lithium Ion batteries "go bad" when they are stored in discharged state. If voltage is too low - undesireable chemical reactions will happen and battery will degrade. If battery is not empty and not used for long time - it will be fine. However batteries are not perfect and they slowly discharge without load.

Generally, NiMH batteries that are properly cared for (charged and used often, stored in a cool, dry place, and not dropped) will last for 500 – 1000 charges or approximately two to three years. Remember, the more you use and charge NiMH, the longer they will last.

Lead-acid batteries lose charge at a rate of about 2-8% per month at 20°C; the self-discharge rate approximately doubles for every 10°C increase in temperature. But if the unused battery is not connected to anything, it will probably be fine after four years if it is fully discharged and then recharged after storage.

Do lithium ion batteries lose their charge when not in use?

Rechargeable Lithium-Ion batteries have a limited life and will gradually lose their capacity to hold a charge. As the battery loses capacity, the length of time it will power the product (run time) decreases. Lithium-Ion batteries continue to slowly discharge (self-discharge) when not in use or while in storage.

Do batteries expire if not used?

Batteries operate on a chemical reaction. It is probably a conservative date, so most batteries will have a full life after that time. Better batteries will show a later expiration date. Alkaline battery life is so dependent on how the batteries are used, and there are no standards.

NiCd batteries were largely phased out in favor of NiMH batteries. These secondary cells boast a higher capacity and are only minimally affected by the memory effect, but they don't have a very good shelf life. Even rechargeable batteries will eventually die, though it may take hundreds of charges before that happens.

The recommended storage temperature for most batteries is 15°C (59°F); the extreme allowable temperature is –40°C to 50°C (–40°C to 122°F) for most chemistries. Batteries should be stored in a dry and cool place, but should avoid freezing. Batteries freeze more easily if in a discharged state.
